Features & Product Details

An External Wastegate (EWG) allows exhaust gases to be diverted prior to entering the turbo; thus creating a quicker turbo spool. GrimmSpeed's EWG Uppipe setup has a larger diameter than the stock internal wastegate. This allows the exhaust gas to be released faster, which improves boost control and maintains maximum boost longer in the rpm range to extends the life of the turbo. Moving the wastegate out of the turbo relieves the turbo from the massive amounts of turbulence that the stock internal wastegate creates.

The EWG Up-Pipe is built from 304 SS with thick 12mm 304 SS flanges that will not warp. The flanges have been CNC cut for perfect tolerances(no laser cutting here!). A flex section has been added; this will extend the life of the product(allows expansion/contraction of pipe without cracking) and will lead to less exhaust leaks. Users should expect gains in the 15-40hp range when tuned for the EWG set-up.

Package Contents:
EWG Up Pipe
Dump Tube
5 Studs for Up Pipe
2 Bolts, Washers, & Nuts

This includes all the gaskets necessary for installation.

This uppipe is not suitable for RHD cars.

GrimmSpeed 44mm External Wastegate Uppipe w/ Dump Tube ( Part Number: 013001)

Awesome 3 years ago

Another very high quality piece from GrimmSpeed! Bolted up to the stock manifold and Blouch 20G-XT no problem! Was difficult trying to get this in from below, but then tried from above - dropped right in with the turbo out! My Tial 44mm EWG fit right up to it, though there was only one way to position it and have the dump tube come out where it should while not hitting anything. I'm not sure if it's due to the larger turbo exhaust housing(upgraded from TD04 to Blouch 20G 8cm at the same time) or due to this pipe, or both; but the exhaust tone definitely has a little more growl to it now. I read in other reviews that the dump tube for the EWG is not long enough. I did not have this problem on my 07 WRX. It is positioned just right, between the transmission and downpipe, not too close to either. As a strong recommendation from my tuner(which I am very glad I took), I bought firesleeving for the 1/4" boost line running to the EWG. Very good idea if you are using anything but metal line for the boost control lines.

Very nice product. Welds are perfect, like a piece of art. Only thing I did not like was the lenght of the dump tube. They could hae made it longer, but it works fine.

QUESTIONS & ANSWERS

  • Q: GrimSpeed Uppipe  BoostedWRX043 years ago

    Will this work with a stock turbo and stock wastegate?
    • 0 of 0 people found the following answer helpful

      A:  The stock wastegate is an internal unit built into the turbine housing, it will not work with this uppipe unless you have an external port blockoff.
